Red Hat Security Advisory 2012-0137-01

Red Hat Security Advisory 2012-0137-01 - TeX Live is an implementation of TeX. TeX takes a text file and a set of formatting commands as input, and creates a typesetter-independent DeVice Independent file as output. The texlive packages provide a number of utilities, including dvips. TeX Live embeds a copy of t1lib. The t1lib library allows you to rasterize bitmaps from PostScript Type 1 fonts. The following issues affect t1lib code: Two heap-based buffer overflow flaws were found in the way t1lib processed Adobe Font Metrics files. If a specially-crafted font file was opened by a TeX Live utility, it could cause the utility to crash or, potentially, execute arbitrary code with the privileges of the user running the utility.

Red Hat Security Advisory 2012-0062-01 - The t1lib library allows you to rasterize bitmaps from PostScript Type 1 fonts. Two heap-based buffer overflow flaws were found in the way t1lib processed Adobe Font Metrics files. If a specially-crafted font file was opened by an application linked against t1lib, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. An invalid pointer dereference flaw was found in t1lib. A specially-crafted font file could, when opened, cause an application linked against t1lib to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
